Class NoMergeScheduler

A MergeScheduler which never executes any merges. It is also a singleton and can be accessed through INSTANCE. Use it if you want to prevent an IndexWriter from ever executing merges, regardless of the MergePolicy used. Note that you can achieve the same thing by using NoMergePolicy, however with NoMergeScheduler you also ensure that no unnecessary code of any MergeScheduler implementation is ever executed. Hence it is recommended to use both if you want to disable merges from ever happening.
